regarding one of my computers:
Latest TT, CPU & GPU temperature reading via external with OHM
CPU AMD Ryzen 3700X - GPU AMD Radeon RX 6600 XT
one issue with this computer that most of the times after reboot computer TT only shows the CPU temperature with loos of data in the TT external tab in the GPU, if TT killed and restarted it starts showing the correct readings, it has been this for last at least three version of TT
